In this paper we examined alternative policies that would expand eligibility for marketplace tax credits to people below 100% of the federal poverty level. We use three different subsidy schedules: the ACA subsidy schedule, enhanced premium subsidies and finally enhanced premium as well as cost sharing subsidies. We show that between 3 and 5 million people would gain coverage. The least generous subsidy option would cost 181 billion over 10 years while the most generous option would cost $335 billion over 10 years. Increasing the federal matching rate for Medicaid expansion enrollees to 100% to preserve equity among states would add $145 billion over 10 years.
